I’d be confident that they were mate yes. That’s why when I looked at making some universal 280/300 brackets, we were going to have them hard anodised.

Failed Brembo brackets
- Thread starter Tim.
- Start date
5xxx and 6xxx have good resistance and are suitable for marine applications, 5xxx are better though.
Making them out of steel is no problem, I can do some to mount milled calipers to 300 discs is anyone wants to got up from 280 discs.

Brembos bolted through and then bolted through again. No threads on the brackets so just an extension lump of metal

Not a good sight and concerning about the potential consequences! I had the PMS conversion but swapped to a 280 set up last year. TBH I don’t know who made them but they look in good order ATM. Maybe they were from this batch?!
Alloy cleaning fluids (wonder wheels etc) must make a difference on these due to the materials they’re made of?
Are there any 280mm brackets being made new by any reputable suppliers ATM?

I've been searching for 280mm brackets but can't find any...
Don't want to run 16's, if anyone finds some let me know!

I don’t have them yet but when I do get hold of them I’ve got no problem sending them your way if it’s going to help ensure this kind of issue is avoided in your version. I’d definitely be interested to hear the thoughts of an expert too.
@Tim. Posted this in Facebook and a guy on there said he makes them. Reputable though? Who knows. PMS may have been wise to stay away from the 280 set up, probably more so to manufacture from steel. Apart from the group buy on here I've only seen Tessa Motorsport making aluminium 280 brackets, and I don't think they are at the moment.
I planned to make some for myself in my spare time at work. I offered to make some for @Radugns after he got ripped off trying to buy some brembo calipers on here and I wasn't in a position to fit them myself, so he's been my Guinea pig too?.
Am I a reputable person to be making these? The potential for failure is scary, we can all see that. I've been a machinist 27 years now and I've machined everything from lead to inconel and made parts for military, cars, cranes, bridges, mines, construction equipment, subsea oil, nuclear and god knows what else! Who machined the ones you are using right now? Who machines the PMS ones? I can make them and I'm confident they will be upto the job, but I offer no guarantee and you run them at your own risk. If anyone is bricking it right now I'd advise going back to standard calipers. Otherwise feel free to pm me and I'll try to help out.
Mate, since I was a child I own some RC models, and currently own a small CNC that can mill aluminium ( plastics and so, but no steel or iron ) and design parts for my RC cars, none of them failed. And if someone says there are small forces, think of an 5kg object traveling with over 60mph and and jumps all rollover all the time.
Those brackets you provide to me are absolutely beautiful and beyond that are very tough. Back in 2012 (iirc) I build a bracket for adding rear calipers to a skoda fabia.
They were from 7075 aluminium, but without any paint or any anti corrosive products. It holds fine even today, I sold the car to a rent-a-car.
I am pretty sure the aluminium brackets will hold fine, but the problem was 99% over tighten the screws, and by that the pressed aluminium was beyond its properties.
And that was true, @OssPoop send me a pair of brackets to test and offer him a feedback. And I was very pleased and confident in those after I saw them that I've painted them before test fitting on the car.
If they are mill correctly, with using radios on edges (fillet edges?) they will hold up forever.
I am very very happy with them, although I prefer a little bigger lip on the discs and have a better caliper clearance. Maybe the Turinis will fit better than oz f1, not sure until next week.
Also, in Romania is "illegal" to change the brakes on your car, but when the MOT inspector saw then, genuine renault calipers, color match brackets and the brake efficiency was better then standard brakes, he has no problems with them.

If you do end up making 280mm brackets anodised, add me to the list of potentials.
You don’t need anymore ?
Why not? There's always something different to try??

Whoa! This looks like a close call. We manufacture our top mounts from 7075 and it corrodes very quickly so we cover them in oil and get them hard anodised as soon as we can.
Our brake brackets are steel and zinc plated with a colour passivation but even after the salt gets through the zinc they will last a lot longer than the rest of the Clio they are bolted to, being 25mm of billet steel! We don't make brackets for 280mm discs as these calipers and the pad shape aren't the best for going down to such a small size disc.
I would also make sure you purchase brake brackets from a company that is properly insured to design, make and sell safety critical parts, unlike many of the ebay sellers!

Are these the same as yours that have failed? They where made by Chris Powell off here.

Look very similar to me, and mine were also from Chris.
Great ?
They should be OK for a couple of years. Maybe.
Just get them hard anodised and they should be OK.
They have been fitted for 20k on a phase 1 I have just purchased. Was going to swap the setup onto my LY. Little nervous as to what I’m going to find when I take the wheels off ?
Wait, another phase 1? Seriously, get help man ???.
Please share pics when you do look at them then.
It was in the pic I posted a few days ago ? the iceburg on the grass.
Here you go. Little bit of surface i wire brushed off but the rest is solid.

Painting on the aluminium is not that easy, you need epoxy primer, very clean surface (sandblasting will be better) and then some finish coats. But this will not prevent scratching where the bolt head came into contact with bracket and could cause the same issues. If yours are fine now and are made out of 6000 series ( not 7000) aluminium, just get them anodized.

Only just discovered this thread. Mine was just surface corrosion. I have caked them in copper grease to try and remedy the issue but will have to keep an eye on them for sure. Must be from the same supplier as OP’s?

Those not look great imho.

thanks.
Will get them off and inspect. Obviously would have to get the steel stud pressed out prior to any anodising wouldn’t I. Assuming they’d take it lol.

Totally agree. Not happy with them. Car won’t be moving much between now and next summer so plenty of time to fix. Will follow this thread
I would buy new brackets either from anodized aluminium or steel (painted)

Hi mate, I can’t right now but I’ll try and remember later on - I think there were a few different threads / group buys started by Chris Powell.
thank you.
Wrong material and not enough research. 'Oooh aero grade aluminium, that's gotta be good!'. Yeah, for a plane maybe😂.
